Buonconsiglio Castle was originated from a fortified building was erected in the 13th century next to the city's walls. This first building was called Castelvecchio ('Old Castle'), and was the seat of the Bishopric of Trent from the 13th century onwards to the end of the 18th century. The castle is composed of a series of buildings of different eras, enclosed by a circle of walls in a slightly elevated position above the town.
The Castelvecchio is the oldest and most dominant building of the entire housing development. The Magno Palazzo is the 16th expansion in the forms of the Italian Renaissance, wanted by the Prince Bishop and Cardinal Bernardo Clesio (1485-1539), the third part, in the southern end of the complex is the known Eagle tower, which preserves the famous Cycle of the Months, one of the most fascinating pictorial cycles of profane the late Middle Ages.
Bishop George of Liechtenstein was the first to enlarge the castle, in the late 14th century, turning it into a well-styled residence. The Castelvecchio was further modified by Johannes Hinderbach, who had the double loggiato and the Gothic entrance gate built. In the first decades of the 16th century, Bishop Bernardo Clesio had a new residence, called Palazzo Magno ('Grand Palace') built in Renaissance style alongside the old castle. The last great addition was the so-called Giunta Albertiana, from the name of Bishop Francesco Alberti Poja (1686), with which the Castelvecchio and the Palazzo Magno were united.
The castle remained the seat of the Prince-Bishops until 1803. Used by the Austrians as military barracks and, later, as a jail, it decayed. In the 1920s, when Trento was returned to Italy, it became seat of a National Museum and was restored. Since 1992 it is home to the Provincial Gallery of Art.
According to legend, it was connected by a secret tunnel to the city's cathedral, which allowed the prince-bishops to move unseen between them.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
